Description 594-597
A new improved polyurethane materials was studied to improve the strength of paper, delay the aging of paper, solve
the problem of poor permeability of traditional resins to paper, and meanwhile to provide basic data for industrial design
and applications, the surface tension of composite solutions consisting of nano-SiO2-based polyurethane, organo siliconbased
polyurethane and epoxy cyclohexane-epichlorohydrin polyurethane dissolved in ethyl acetate had been measured
at temperatures ranging from 283.15 K to 308.15 K. The surface tension was fitted with the related equation between
surface tension and temperature under normal pressure. The mean relative deviations between the calculated value and
the experimental value were derived. The results showed that the model estimation of the surface tension of the
composite solution were in good agreement with the experimental data, the paper coated by the polyurethane materials
had better mechanical property. Therefore, the prepared polyurethane material has great application prospects in the
protection of paper.
